To all whom it may concern:

Be it known that I, HANS A. MEINHARDT, a citizen of Germany, residing at Pittsfield, county of Berkshire, and State of chusetts, have invented a new and Improved Slide for Motion-Picture Machines, of which passing the operators finger he minute hand hen set by rotating disk by a finger introduced from th of the p This invention relates to a slide of novel construction adapted to be exposed in a moving picture machine between the withdirectly after the withdrawal-of one film and prior to the Introduction bf the next film.

thus Waiting, so as to While awa and the time to simultaneously impart instructive I cla1m:

1. A slide for moving picture comprising a transparent plate, a clock dial represented thereon, an arbor carried by the plat; and centered within the dial, an hour an In the accompanying drawing: Figure 1 is a front elevation of a slide embodying my invention; Fig. 2 a horizontal section on line 22, Fig. 1; Fig. 3 a vertical section on line 3 3, Fig. 1, and Fig. 4 a front view of the rotatable diskdetached.

e slide comprises essentially a plate 10 made of mica or other transparent material and provided with a surrounding frame 11. pon plate 10 there is represented preferably near one of the edges thereof, the dial 12 o a clock, such dial being thus integral with the plate and being likewise transparent. Throhgh the center of dial l2,there passes an arbor 13 carrying at its forward end, i. e." in front of plate 10, an hour hand 14. Back of plate 10, there is mounted on the a rotatable transparent disk 15 upon WhlCh is represented by t e arbor back of the plate, and an opaque minute hand represented on the disk.

2. A slide or moving picture machines, comprising a transparent plate ger notch and a dial represented in proximity to said notch ried by dial, a transparent rotatable disk carried by the arbor back of the plate, said disk .being partly .exposed through said notch, and an opaque hand represented on the disk.

3. A sli e or moving picture machines comprising a transparent plate having a finger notch, a dial and display matter represented on the plate, an arbor carried bythe plate and centered within the dial, an hour hand mounted on the arbor in front of the plate, a transparent rotatable disk carried ,by the arbor back of the plate, said disk being partly exposed through said notch, and an lppaque minute hand represented on the dis 4.
